If this computer has a 16?bit data bus and can access bytes and 16?bit words, suggest ways in which the byte/word selection may take place.

What will be an ideal response?

One possible technique (we will use a 32?bit system) is to remove address lines A00 and A01 that define (select) bytes xxx0, xxx1, xxx2, and xxx3 and use three bytes strobes Byte0, Byte1, Bytes2, and Bytes3 instead. During a memory access, the address on address lines A31 to A02 selects a 32?bit word address and then the four byte strobes can be used to select any byte or combination of bytes in that word.
